That... Is seriously disturbing! Good find (and conversion)
-
Great news! Thanks Just to add about generator folder to everyone that you can just copy the generator folder to beta9 version from one of the older versions as that hasn't changed.
-
Oh, yes... you're on Windows 7 aren't you. Probably something to do with newer Windows versions then 🫣

Great you got a 64 bit version working! I'm testing beta8 version with 8 threads and 100000 solutions (yeah, that probably is dumb) on a picture that's been running days now. It did start around 1GB memory usage, but it's surpassed 3GB now. However, with /continue it is no big deal from previous experience if RastaConverter stops - The memory use starts off low again and continues with no seeming issues. Not Ilmenit's problem but RCGUI may behave weirdly with beta9? Will fiddle to see what works nicely or not (apart from renaming executable to RastaConverter.exe)

RastaConverter Beta8 Release 2 Recompiled Windows version for largest possible 32-bit program memory usage Arsoft RCGUI.exe fix for CPUs with more than 16 cores (threads) RastaConverterBeta8R2.zip
-
There definitely seems to be diminishing returns on just adding more threads to process a single picture. I wonder now how sane it is to default the GUI to the number of threads of the CPU especially for a 32 bit program. The memory usage continues to slowly grow too the longer it runs (which is slightly concerning, but may be the expected caching behavior). In another year or so CPUs will have thread counts that will easily eat the max 4GB.
-
OK, it is running out of memory with that many cores (threads). I was able to recreate it by specifying 32 threads on the command line 32-bit Windows programs can usually only use 2GB and task manager showed it going up to about this before RastaConverter died. Have just learned there is a compiler/linker option which allows 4GB though: /LARGEADDRESSAWARE @Stephen The 32 thread test worked after compiling Beta8 with that option and I've attached it here if anyone wants to try it. RastaConverter.exe
-
I don't know why the converter may crash with more threads unfortunately. Didn't touch that code. Wonder if beta7 has the same trouble? The speed could depend on caching the solutions for scan lines. I've noticed things often start slow with large number of solutions selected but things speed up as they "converge" more. That's only an observation as I don't really understand the hill climbing algorithms or caching parts of the program myself (yet! Maybe one day I'll get there) Maybe it doesn't like a mix of P cores and E cores. intel thread director could highlight something It's only a 32 bit program (couldn't make a 64 bit build) possibly some windows 32 bit restriction. Can't say I've seen it use loads of memory though
-
Yep, that's him. He has done tons of Atari stuff over the years. Laura is really good, but I admit I didn't play much. @BeeblebroxThe problem that the new version fixes is if you have a processor with more than 16 cores, (which more and more processors are doing these days of course). It errors when you run the GUI and you can't get more than 16 cores working on the conversion.
-
RCGUI.exe high core processor fix Arsoft made the nice GUI front end for RastaConverter Windows users many years ago, but no longer has the source code. The attached is a fixed version though which you can copy into your RastaConverter folder to replace the existing one if you have the problem. Thanks to @Stephen and my brother Ben who knew the .net/vb.net/c# to make it work again after messy decompile due to no source code RCGUI.zip

Hi Mods, Al, Every private message I'm trying to send people is giving the above error. I know the message can mean their mail box is full but it does the same for everyone I tried including to myself. Maybe my account is broken (or I need to buy a proper subscription again!) Any advice please? Thanks Kind regards Chris Um, nevermind, I shouldn't put an @ in front of the name in private messages like elsewhere. My bad.

Hitchhikers Guide to the Galaxy! Very British absurd comedy. But is very funny to many. 😀 https://en.m.wikipedia.org/wiki/Zaphod_Beeblebrox

So when you try and run it, it just immediately crashes sometimes, but usually it runs fine. Weird! Maybe see if you can use @ivopLinux version. You'd probably need similar instructions to make it as @dmsc for your system. (Unless someone has already compiled a version for your Linux distro they can send you)
-
@dmsc any suggestions? I can only speak for the Windows compile which assumes SSE2 capable processor. I know there's lots of different Linux distro but assume other people have had success though.
-
Is that on your Linux or do you also use Windows version?
-
where can you learn the commands of mad-asm please?

they look familiar. I remember sharing those quite a few years ago now. I had got a trial version of the Intel Compiler to try learning something. That didn't work out, but I played with various processor options and Profile Guided Optimization for RastaConverter. There weren't any changes over beta7, but the compiler just did an outstanding optimization for speed on the code. The Intel compiler isn't the same anymore (but is free) and I can't get Profile Guided Optimization to work with RastaConverter and Visual Studio anymore. But it has been compiled with the best settings I could find for speed.
-
That's great. I see it now. Thanks @ilmenit
-
Nice! Is that rate what you normally get or just a fluctuation with 16 threads or more? My best machine only manages peaks of 90 000, but it is old now.
-
At some point I hope Ilmenit will be able to merge the new version source code changes into his GitHub repository if things look ok.
-
I think that error is coming from the separate GUI front end program. Are you able to try same options from command line to confirm? Unfortunately I don't know anyone who has the source code for the front end.

RastaConverter Beta8 Testing I've been messaging people who might know a bit about the RastaConverter source code to see if some simple hack or work-around could be done to help stop those ugly horizontal line artefacts it does sometimes which only show up when viewed on real Ataris or modern emulators After being pointed to an idea in the right kind of direction and place (thanks @phaeron) I've done a small hack to the Evaluator function which I'm getting some feedback from @ilmenitabout. The idea (which has been suggested by others in the past too) avoids a complete rewrite of some things, and makes RastaConverter give a bad score to scan lines that meet certain fairly simple conditions instead. In the meanwhile I've been trying it out myself with some good results, and as you can see here recently, have let @Atari8man2004 have at it, as he has a powerful rig and lots of pictures on the go, so would likely notice any problems sooner than most. So far so good by the looks of it! Thanks very much for testing. So sharing it with you all here now. @ilmenit has been kind enough to try getting his RastaConverter development environment set up again to check things out properly, which we've both found is unfortunately a pain to get working now on newer environments due to the age of the libraries and things used originally. Although it is only quite small changes, please let me know if you come across any new weirdness with this version, as it is very possible for me to have made mistakes with this, not being too familiar with the codebase or C++ (learning a lot from trying this) Thanks to @drpeter for managing to find an example of a wrongly self overlapped player and of course for highlighting the artefact issues in the first place, what causes them at a deep level and how to try and fix them (building on @phaeron findings in his Altirra Hardware Reference manual, making Altirra more accurate, and prompted at least partly by... what RastaConverter actually shows on a real Atari) Kind Regards Sheddy RastaConverterBeta8.zip sheddy_ding.xex

Yeah, I know, no music, but it has the rest covered.
